This question is aimed at Dave Haynie.

In a previous message, you mentioned that you though about tricks for solving
the Forbid()/Disable() problem using virtual machine emulation. My question is,
how?

I though about this once again, and once again I came to the conclusion that
it does not matter wether you can trap the Forbid()/Disable calls, since the
problem is not that multitasking is disabled, but rather that we do not know
*why* it is disabled. Thus we do not know what reparative action to take, and
thus wether we are allowed to perform page swapping or not.

Valentin
